Light period once I got my period back after being 31 days late

Hi everyone! Has anyone experienced this? I had light period after I missed my last one.

Day 1 - reddish brown, light - did not last a day

Day 2 - nothing in the morning then I was having same reddish brown blood at night but just small amount

Day 3 - same as above

Day 4 - dark brown - almost black blood.

Of all the days above, my period has small clots.

Have you ever experienced this?

Im still feeling bloated since I feel I have NOT expelled all the dirty blood in my system lol. Or maybe because Im stressing too. Ive read stress can also make you bloat.

Anyway... please share your thoughts!
